Description

FSR402 Round Force Sensor – Force Sensitive Resistor

The FSR402 is a round force-sensitive resistor (FSR) that changes its resistance based on the pressure or force applied to its surface. With a 12.7mm (0.5″) diameter sensing area, this compact and lightweight sensor is ideal for detecting touch, pressure, and force in interactive projects, robotics, musical instruments, medical devices, and more.

It is easy to interface with microcontrollers such as Arduino, Raspberry Pi, and ESP32, making it popular for DIY electronics and human-machine interaction applications.

Key Features

Force-sensitive resistor – resistance decreases with increased pressure
Round sensing area (12.7mm diameter)
